COMPOSITION FUEL.

fPECIFICATION forming part of Letters Patent No. 784,302, dated March'7, 1905.

Application filed March 10, 1904:. Serial No. 197,472.

To rtZZ whom, it Duty concern.-

Be it known that I, CHARLns H. CARPEN- TER, a citizen of the UnitedStates, residing at South Bend, in the county of St. Joseph, in the 5State of Indiana, have invented certain new and useful Improvements inComposition Fuels; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form part ofthis specification.

My present invention relates to improvements in artificial compositionfuels specially designed for domestic heating and in the process forproducing the same.

The primary object of my invention is to provide cleanly, sootless, andeconomical artificial fuel the ingredients of which are found in allparts of the country and can readily and conveniently be combined,possessing a very high degree of heating power and which is made up intosmall blocks in a form convenient to handle and use, is practicallyodorless in burning, produces no cinder-s, and leaves no clinkers.

Another object is to provide a composition fuel resembling anthracitecoal in weight, appearance, and heating power and whose componentelements are so united as to preserve and distribute the volatileelements throughout the mass, thereby conserving its heating units.

The novel features of my invention reside in the composition produced bythe union of the component elements and in the process by which thisfuel composition is produced.

My improved artificial fuel consists in the following ingredientscombined in substantially the following proportions to each ton of thefuel: common peat or muck, nineteen hundred and fifty pounds, commonsalt, ten pounds, powdered rosin, forty pounds. The above ingredientsare thoroughly mixed in any proper manner. The peat usually containsmoisture, which is removed before mixing, leaving it properly dried,after which the composition is made up into any suitable form bysubjecting it to a pressure by suitable means of approximatelytwenty-four thousand pounds to the square inch. The powdered rosin whenproperly distributed throughout the mass serves as an efiicient binder,and the ingredient of salt performs the function of eliminating the sootin burning.

My invention is preferably pressed into small blocks resembling in sizethose of eggeoal and stove-coal, though it may with equal facilitybemade into blocks of any desired form or dimension. IV hen thecomposition is subjected to the intense pressure specified, the volatilematter of the peat which would otherwise escape and be lost isdistributed throughout the mass and preserved, thereby materiallyincreasing the firmness, cleanliness, and eificiency of the fuel.

My improved fuel thus produced resembles hard rubber in appearance andsolidity and burns like anthracite coal, whose heating power itapproximately equals, but burns without appreciable odor, makes neithersparks nor cinders, in combustion is cleanly, sanitary, and nearlysmokeless, leaves no clinkers what ever, and has been proven by numerouspractical tests to be superior in heating powerto soft or bituminouscoal, and nearly, if not quite, equal to anthracite coal.

' This artificial fuel is of course equally Valuable for the generationof steam and for any and all purposes for which fuels are generallyemployed.

, The component elements of this fuel are everywhere cheap and abundantand can be manufactured from the materials at hand or convenientlyaccessible in any part of the country.

\Vhile the exact proportions of the above ingredients are not absolutelyessential to the formation of my improved product, yet it is believedthe best results are secured by substantially the proportions abovespecified, though I do not desire to be understood as limiting myself tothe precise proportions described.

Having thus described my invention and the manner of employing the same,what I desire to secure by Letters Patent is 1. A composition forartificial fuel consisting of peat or muck, salt, and powdered rosin,

- in substantially the proportions specified, and

so compressed into a solid mass or compound as to distribute thevolatile and resinous matter of the composition throughout the mass andretain the same.

2. An artificial fuel consisting of a hard compressed amorphous mass inwhich the easily volatile matter is retained by high pressure, andconsisting of peat, salt and rosin mixed in substantially theproportions described, and compressed by high pressure.

3. The process of making artifical fuel consisting of mixing peat, saltand rosin in the proportions specified, and then compressing the sameinto a hard amorphous mass in which the easily volatile matter isretained by high pressure and distributed throughout the mass.

4:. The herein-described process of making artificial fuel Whichconsists of mixing peat, salt and rosin together, and then forming thesame into hard amorphous masses by high,
